Detailed ways

The technical solutions in the present utility model are further described below with reference to the accompanying drawings and embodiments.

As shown in FIG. 1, an embodiment of the present utility model proposes a computer cable, including:

The core wire, including the guide core 1 and the insulating layer 2 wrapped outside the guide core 1;

The first cladding layer 3 is wrapped around the twisted at least two core wires, and together with the core wires inside form a conduction unit;

The second cladding layer 4 is wrapped around the twisted conductive units;

The filling layer 5 is filled between the conductive unit and the second cladding layer 4;

The shielding layer 6 is wrapped outside the second cladding layer 4;

The armoring layer 7 is wrapped outside the shielding layer 6;

The sheath layer 8 is wrapped around the armor layer 7 , and the outer surface of the sheath layer 8 is provided with heat dissipation ribs 9 .

To a certain extent, the heat dissipation ribs leave a certain space for ventilation and heat dissipation for the bundled cables, which improves the heat dissipation problem of the computer cables and increases the service life of the cables.

Preferably, the interval between the heat dissipation ribs 9 is smaller than the width of the heat dissipation ribs 9 or greater than twice the width of the heat dissipation ribs 9 . When the space between the heat dissipation ribs 9 is smaller than the width of the heat dissipation ribs 9, it can prevent the heat dissipation ribs 9 from extending into the space between the heat dissipation ribs 9 of the adjacent cables and affect the heat dissipation effect; Even if the heat dissipation ribs 9 extend into the space between the heat dissipation ribs 9 of the adjacent cables, there is still a lot of heat dissipation space reserved.

Preferably, the heat dissipation ribs 9 spirally extend along the outer sidewall of the sheath layer 8 . The spiral extension makes the interval between the heat dissipation ribs 9, that is, the distribution of the heat dissipation space more uniform, and leaves a channel for the entire bundle of cables to communicate with the air outside the bundle to circulate and dissipate heat.

Preferably, the heat dissipation rib 9 extends along the outer side wall of the sheath layer 8 in a segmented spiral, and the spiral directions of adjacent segments are opposite. The staggered extending directions can more effectively reduce the probability of the heat dissipation ribs 9 extending into the space between the heat dissipation ribs 9 of adjacent cables.

Preferably, the cooling ribs 9 are wrapped with reinforcing wires 10 . Improves the cable's tensile properties and reduces possible damage to computer cables when they are pulled.

Preferably, the reinforcing wire 10 is nylon wire and/or glass fiber. The selected reinforcing wire 10 is a material with high strength and not easy to be stretched.

Preferably, the sheath layer 8 is polyperfluoroethylene propylene. Polyperfluoroethylene propylene has good flame retardant and high temperature resistance properties, which can meet the needs of computer cables.

Preferably, the shielding layer 6 is one of braided copper wire, tinned braided copper wire, copper tape, and copper-plastic composite tape. Braided copper wire is enough to reduce signal interference.

Preferably, the armor layer 7 is a steel tape. The steel tape is used as the armor layer 7, and the wrapping is more dense, which is conducive to heat dissipation and can play a certain degree of flame retardant effect.

Preferably, the insulating layer 2 is selected from polyperfluoroethylene propylene or cross-linked polyethylene.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should The technical solutions are modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and all of them should be included in the scope of the claims of the present invention.
